[0032] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate the same or corresponding parts and features.
[0033] According to an exemplary embodiment, Figure 1 1 shows a vehicle 10. The vehicle 10 includes a body 12 supported by a plurality of wheels 14. A powertrain 16, such as an internal combustion engine, an electric motor, or a hybrid powertrain, is operatively connected to the plurality of wheels 14 to drive the plurality of wheels 14. The body 12 defines a passenger compartment 18 within the body 12, and one or more doors 20 are provided for passengers to enter and exit the passenger compartment 18. A plurality of rows of seat assemblies 22 are positioned in the passenger compartment 18.
[0034] Reference now Figure 2 , the seat assembly 22 includes a seat 24, which includes a seat base 26 and a seat back 28. In some embodiments, a seat back hinge 30 connects the seat back 28 to the seat base 26, thereby allowing the position of the seat back 28 relative to the seat base 26 to be adjusted. The seat 24 is connected to a seat adjuster 31, which allows the seat position to be adjusted forward and rearward relative to the vehicle body 12. The seat adjuster 31 includes a floor rail 32 fixed to the vehicle body 12 and a seat rail 34 operably connected to the seat 24 and slidably mounted to the floor rail 32. As shown in FIG. Figure 3 As shown, the seat adjuster 31 includes a seat motor 36 that pushes the seat 24 forward and backward, and a seat rail 34 and a floor rail 32 that guide the forward and backward movement.
[0035] The seats 24 may be operated in a cargo mode, such as Figure 4 and Figure 5 . The seat 24 is operably connected to the seat rail 34 via a front bracket 38 and a rear bracket 40. The front bracket 38 is connected to the seat 24 via a front seat pivot 42 and to the seat rail 34 via a front rail pivot 44. Similarly, the rear bracket 40 is connected to the seat 24 via a rear seat pivot 46 and to the seat rail 34 via a rear rail pivot 48. In order to move the seat 24 from Figure 4 The normal position shown is moved to Figure 5 In the cargo position shown, the seat back 28 is positioned as shown in FIG. Figure 5The seat 24 moves downward toward the seat base 26 about the seat back hinge 30 by rotating in the counterclockwise direction shown. In addition, the seat 24 moves rearward and downward toward the floor rail 32. This movement is achieved by moving the front bracket 38 about the front rail pivot 44 and by rotating the rear bracket 40 about the rear rail pivot 48. Figure 5 In the view of FIG. 4 , the rotation of the brackets 38 and 40 about the respective guide rail pivots 44 and 48 is in a clockwise direction.
[0036] In some embodiments, the movement is driven by an adjustment motor 50, which is operably connected to the rear support 40 at, for example, the rear rail pivot 48. Activation of the adjustment motor 50 drives the rear support 40 to move about the rear rail pivot 48. Figure 4 The normal position and Figure 5 The movement of the seat base 26 in the rearward direction as a result of the movement of the rear support 40 about the rear track pivot 48 pushes the front support 38 about the front track pivot 44. In some embodiments, the adjustment motor 50 can be the same motor as the seat motor 36 and can drive the forward and rearward adjustment of the seat position and can also drive the seat 24 to move into the cargo position. In one embodiment, when the seat 24 moves through its fore-and-aft adjustment range 52 and reaches the rearmost point 54 of the adjustment range 52, the seat motor 36 moves the rear support 40 about the rear track pivot 48 via, for example, continued activation of the adjustment switch 56.
[0037] Although in Figure 5 In the embodiment of FIG. 5 , the movement is achieved by adjusting the motor 50, but in the embodiment of FIG. Figure 6 In another embodiment shown, the movement can be achieved by manual operation of the user. In this embodiment, the rear support 40 is locked in place relative to the rear track pivot 48 by a pivot lock 58. When the user releases the pivot lock 58, the rear support 40 is free to rotate relative to the rear track pivot 48, so that the seat 24 can be moved in a certain direction. Figure 4 The normal position and Figure 6 Manually move between the cargo positions shown.
[0038] Reference now Figure 7 In other embodiments, the front bracket 38 includes a bracket pivot 68 positioned along the front bracket 38 between the front seat pivot 42 and the front rail pivot 44 such that a first bracket portion 70 located at a first side of the bracket pivot 68 can rotate relative to a second bracket portion 72 located at a second side of the bracket pivot 68. When the seat 24 is moved to the cargo position, the bracket pivot 68 articulates, which has the effect of further lowering the cargo loading surface 66 of the seat 24 and reducing the cargo surface angle 64 of the cargo surface.
[0039] In some embodiments, the rotation of the seat back 28 is independent of the movement of the seat base 26. However, in other embodiments, the folding of the seat back 28 toward the seat base 26 is associated with the movement of the seat base 26 to the cargo position. Figure 6 As shown, the seat back 28 can be connected to the pivot lock 58 by, for example, a link 60. The link 60 is configured to release the pivot lock 58 when the seat back 28 is folded to the seat base 26, thereby allowing the seat base 26 to move to the cargo position. In other embodiments, the link can be configured to prevent the pivot lock 58 from being released unless the seat back 28 is folded to the seat base 26.
[0040] like Figure 5 As shown, moving the seat base 26 downward and rearward to the cargo loading position via the rear track pivot 48 lowers the cargo loading surface 66 defined at least in part by the rear seat back surface 62 and may also reduce the cargo surface angle 64 relative to portions of the cargo loading surface 66. This results in easier loading of cargo onto the cargo loading surface.
[0041] The terms "one" and "an" do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced item. Unless the context clearly indicates otherwise, the term "or" means "and / or". References to "aspects" throughout the specification mean that a particular element (e.g., a feature, structure, step, or characteristic) described in conjunction with that aspect is included in at least one aspect described herein, and may or may not be present in other aspects.
